(1) A qualified journeyworker or master must supervise the work of an apprentice in the proper ratio prescribed in the registered standard. Supervision means the following:

(a) A journeyworker or master must be assigned to the job site and be able to give direction and check the work of the apprentice except during absences as required in the scope of business and otherwise provided in this chapter.

(2) Except as otherwise provided in this chapter, an apprentice may not work without the supervision of a journeyworker or master while engaging in an activity covered by the apprenticeship agreement or registered apprenticeship standards of the sponsor.

(3) Sponsors employing apprentices in occupations that require a residential focus may work an apprentice in areas of experience with limited supervision based on prior performance and a demonstration of competency.

(4) An apprentice who has completed no less than 70 percent of the apprentice's required term and is completely current with related instruction may work with limited supervision. The apprentice's work must be physically examined on a daily basis by a journeyworker or master for correctness.

(5) During the last 20 percent of the apprenticeship term, an apprentice who is completely current with required related instruction may work without supervision, provided that the apprentice's work will be physically examined weekly by a journeyworker or master, and provided that the apprentice's prior performance demonstrates sufficient competence to perform the work.
